Samsung Error Code C-10
Communication error
Common Causes
- 1Board communication failure
Step-by-Step Troubleshooting
- 1
Turn off the oven at the circuit breaker, wait 5 minutes, then restore power. Samsung dual-oven and slide-in range models have multiple boards that communicate over a serial bus — a power spike can disrupt communication
- 2
Access the control boards by removing the back panel of the range. Samsung ranges typically have a main relay board and a UI/display board connected by a ribbon or harness cable
- 3
Inspect the communication cable between the boards — look for damage, corrosion, or loose connectors. Reseat all inter-board connections
- 4
If C-10 persists after reseating, replace the main relay/power board first (more common failure point), then test. If it continues, the UI board or the harness between them is at fault
Pro Diagnostic Tip
Samsung C-10 on ranges installed on a circuit shared with other major appliances (microwave, dishwasher) is often caused by line noise from the other appliance motor starting. A dedicated 40A or 50A circuit for the range eliminates the interference.
